BRUMADINHO, Brazil—Authorities arrested five people Tuesday in connection with the collapse of a Brazilian mine dam, while the death toll rose to at least 84 and the carcasses of fish floated along the banks of a river downstream that an indigenous community depends on for food and water.
The dam that held back iron ore waste, owned and operated by big mining company Vale SA, collapsed on Jan. 25, burying a company cafeteria and other Vale buildings and inundating part of the small southeastern city of Brumadinho.
